CASEMENT SASH FRAME.

Application filed December 26, 1925. Serial No. 77,780.

In the manufacture or sale of what is known as stock casement sashframes or those ready made for use in a building, it has been customaryand in fact necessary to make two different types of frames; one

a for an inswinging casement sash and the other for an outswingingcasement sash.-

This is due to the fact that the stock or standard casement sash forinswinging or outswinging are of the same dimensions and the standardframe with the dip or inclination of the sill as generally made wouldnot accommodate a casement -sash of the same dimensions used in both theinswinging and outswinging positions, nor is the sill of an inswin ingsash adapted to receive the hardware for an outswinging one. Hence, themanufacturer has been obliged to make two styles of frames and supplythem in'that way to the trade. The dealer of course never knew whichtype would be specified or called for by the architect or contractor andhe found it necessary to carry a stock, which might not be the kind inmost demand. Frequently, the dealer would find himself with a largesupply of one style and an order might be received for the other styleof which he had none. This method, therefore, of making and handling theframes has been not only awkward and inconvenient for the manufacturerand dealer buthas involved considerable unnecessary trouble and ex use.

he object, therefore, of our invention is constructions and combinationsall as here-- inafter described and outjin the claims. In theaccompanying drawings forming part of this specification,

Figure 1. is a perspective view of a sash frame showing an outswingingcasemen sash;

particularly painted inswinging casement sash;

is a vertical sectional view of Figure 4 is a sectional view on the line4+4 of Figure 2;

Figure 5 is-a sectional view on the line 5-5 of Figure 3;

Figure 6 is a perspective view of the auxiliary window sill that is usedwith the outswinglng casement sash and Figure 7 is a perspective view ofthe removable bead that is used with the storm and screen sash for boththe in and outswinging casement sash.

' In the drawing, 2 represents a window sill having at its inner upperedge a rabbet 3 and a longitudinal rib A provided with a substantiallyflat upper surface 5. The inner face of this rib forms the vertical wallof the rabbet as indicated in Figure 2. The outer face of the rib iscurved preferably at 6 andmerges into the outwardly and down wardlyinclined upper surface of the sill. At a point between the rib 4 and theouter edge of the sill a shoulder 7 is formed extendlng lengthwise ofthe sill against which the lower rail of the storm sash is seated. Wehave shown in the drawing the invention applied to a mullion type ofsash in which 8 represents the side jambs; 9, the head jamb; 10 themullion' jamb between the sash; 11, the outer casing and 12, the top orhead casing extending horizontally across the window.

In Figures 1 and 2, we have shown the frame equipped with outswingingcasement sash 13 hinged at 14, and seated against the stop 15 at thehead of the frame and overlapping the shoulder 7 at the bottom. When thesash is mounted to swing out, as described, the screen and storm sashmust, of course, be mounted at the inner side of the frame, and we haveshown in Figure 2, a

storm sash 16 fitting the rabbet 3 in the frame and having its .lowerrail rabbete'd or recessed as indicated to receive the shoulder '4 andform a weatherproof joint therewith.

The standard dimension, however, of the in and outswinging sash is oneand threeeighths inches thick and the window frame is, therefore,rabbeted to receive a sash: of this thickness. The standard dimensionofstorm and screen sash is, however, one and one-eighth inches thick andprovision must, therefore, be made for fitting the storm or screen sashto the rabbeted frame when put in place of the swinging casement sash.\Ve, therefore, provide a head 17 corresponding in thickness to thedifference between the thickness of the easement sash and the screen andstorm sash. This bead, as shown in Figure 2, is fitted snugly againstthe inner face of the rabbeted frame to form a seat for the screen orstorm sash.

In the manufacture of the frame, the head 17 will be placed in the outerrabbet of the frame against the stop 15 as shown in Figure 3, and if aninswinging casement is to be used, the bead will exactly compensate forthe difference in thickness between the storm sash and the easement sashso that the storm sash will fit in its seat perfectly and be flush withthe outer edges of the side and head jambs as shown in Figure 3, thelower rail of the sash being seated against the shoulder 7. When,however, an outswinging casementv is to be used. the bead 17 will beremoved and one end cut otf sulficiently to allow it to be inserted intothe inner rabbet of the frame. If the inswinging casement is used, thehead will be furnished as illustrated in Figure 3, all the parts beingin proper position for this type of sash. In case, however, an out swingis specified, or called for, the bead 17 will be moved to the innerrabbet as described, and then in addition we provide an auxiliary sill18 having a flat upper surface 19 which merges into, and forms, acontinuation of the surface 5 of the shoulder 4, the under surface ofthis auxiliary sill being inclined and curved at one edge to fitthe topof the main sill and the outer face 6 of the shoulder 4. A square outeredge 20 is provided on this auxiliary sill against which the lower railof the outwardly swinging sash is seated, thus forming a' weather-proofjoint at this point and particularly this auxiliary sill provides anormal fiat sill surface for the sash frame when the inside storm sashis removed.

The auxiliary sill has also the function of forming a fiat surface onwhich the casement sash hardware may be mounted, it being impracticableto mount such hardware on the inclined surface of the main sill of theframe.

The rabbet in the head jamb is indicated at 9 adapted to receive theupper rail of the inswinging sash. This rabbet, or a similar one,however, is omitted at the outer edge of the head jamb, the stop 15secured to the under side of the jamb taking its place as indicated inFigure 3, the head 17 being seated against this stop when an inswingingcasement sash is used. The use of a stop in place of a rabbetcompensates for the dip or inclination of the window frame sill. Toillustrate, referring to Figure 2 of the drawing, the frame is shownequipped with an outswinging sash and evidently to use a sash of thesame dimensions as that adapted for inswinging movement, the stop 15must be used instead of a rabbet similar to 9 to compensate for thevariation in level of the lower outer edge of the outswinging sash andthe inner edge of the inswinging This difference in level is indicatedby dotted horizontal lines in Figures 2 and 23. When the outswingingsash is used, then of course, no rabbet is necessary in the outerportion of the head jamb, the stop 15 providing a seat for the upperrail of the sash when used in an outswinging position. '0 regard thisfeature as an important one in the case as it adapts the easement sashfor either an outswinging or inswinging position without the necessityof changing the length of the sash to compensate for the tilt or drop ofthe window sill.

Generally, in manufacturing the sash frame, the heads will be put inplace by the manufacturer in the outer rabbets of the sash frame, to beremoved therefrom, cut off, and then placed in the inner rabbet when anoutswlng is desired, but we may prefer to furnish the auxiliary sill incomparatively long strips so that when there is call for them, thedealer may have them cut up and fitted to the sill of the frame to adaptan inswinging casement for an outswinging one.

We claim as our invention:

1. A sash frame comprising a sill and side and head jambs, the inner andouter portion of said sill and jambs being adapted respectively formounting an inswinging or outswinging casement sash of substantially thesame dimensions therein.

2. A sash frame comprising a sill, outwardly and downwardly inclined,and side and head jarubs, said head jamb having a stop on its under sideand also having a rabbeted inner portion, said stop and rabbet adaptingthe frame to receive an outswinging or inswinging casement sash with thesame height'of sash in either position.

3. A sash frame comprising a sill and side and head jambs therefor, saidsill bein outwardly and downwardly inclined, an said head jamb having astop to receive the upper rail of the outswinging sash, the distancebetween the under side of said head .jamb and the frame sillcorresponding to the distance between the inner surface of the sill andthe seat of the inswinging sash in said head jamb.

4. A sash frame comprising a sill and side and head jambs therefor,adapted to receive either an in or outswinging casement sash, and meansadapted to be moved from one jamb to the other to adapt either inside oroutside edge of jamb to receive a storm or 1 was screen sash of lessthickness than the case ment sash.
